i wish i knew about this 15 Years ago.. 

Hello, I'm under the water.

1:36 NOOOO!

I remember doing this in Multiplayer back in 2009. I would troll the entire lobby.

Bruh , you sure are working hard for these

Oh, this is better than I expected. I thought that would like under that abandoned wooden pier in Beechwood City where you end up under the map/ground in the water until you reach the end of it in a square shape and you can see water in GTA 4 is just a thin layer of water aspect only observable from the above.

Mmm, finaly, diving in gta 4 without mods

This glitch is dope

When Niko shootin from RPG its looks like from movie Tenet

So they modelled the bottom of the river or whatever but didn't allow you to go underwater. Odd, ngl.

Imagine setting up a hang out under the water

@fiqql Are you playing GTA IV Steam version (Complete Edition with GTA IV and Episodes from Liberty City)?

Wow, cool!

You parents must be proud if they're still alive.
